6.9 Vocabulary (handout given to students)

Capacity - A measure of the ability to receive, hold, or absorb volume.

Length - A measure used as a unit to estimate distances.

Weight - Weightis determined by the pull of gravity on the mass of an object.The weight of an object

changes dependent on the gravitational pull at its location.

Mass - Mass is the amount of matter in an object. The mass of an object remains the same regardless of its location. In everyday life, most people are actually interested in determining an object’s mass, although they use the term weight, as shown by the questions: “How much does it weigh?” versus “What is its mass?”

Volume –The amount of space that a three dimensional figure contains. Volume is expressed in cubic units, it tells you the number of cubes of a given size are used to fill the figure.

Area – The product of the length and the width (A = lw). The area of a triangle is one half of the measure of the base times the height: A = bh, or A = bh ÷ 2.

Square Unit – Units used when measuring the area of a two-dimensional figure.

U.S. Customary System –System of measurements using inch, foot, yard, mile, fluid ounce, cup, pint, quart, gallon, dry ounce, pound, and ton.

Inch –measurement, about the width of a quarter

Foot –used to measure length, equal to 12 inches.

Yard –3 feet, approximate distance from nose to fingertip for the average adult

Mile –used to measure distance, equal to 1,760 yards

Ounce (oz) – measurement for liquids or solids; (p. 470) fluid ounce (fl oz), about 2 tablespoons of water; dry ounce (oz), about the weight of a pencil

Pound (lb) –used to measure mass, 1 pound = 16 ounces, 1 package of notebook paper

Ton (T) –solid measurement, 1 ton = 2,000 pounds, average passenger car

Cup (c) –liquid measurement, 1 cup = 8 fluid ounces, coffee cup

Pint (pt) –liquid measurement, 1 pint = 2 cups, small ice cream container

Quart (qt) –liquid measurement, 1 quart = 2 pints, small plastic jug of milk

Gallon (gal) –liquid measurement, 1 gallon = 4 quarts, large plastic jug of milk

Metric System –A decimal system of units based on the meter as a unit length, the gram as a unit mass, and the liter as a unit of volume.

Meter (m) –basic unit of length in the metric measurement system, equivalent to 39.37 inches or just more than 3 feet.

Centimeter (cm) –metric measurement, 2.5 centimeters = to 1 inch, half the width of a penny

Kilometer (km) –metric measurement for distances, 6.2 km = to 1 mile, six city blocks

Millimeter (mm) –length measurement, 25 millimeters = 1 inch, thickness of a dime

Liter (L) –liquid metric measure, 1 liter = 1 quart, 1 small pitcher

Milliliter (ml) –liquid metric measurement, 1 milliliter = 0.03 fl oz, an eyedropper

Gram (g) – metric measurement for solids, a paper clip

Kilogram (kg) –solid metric measure, 1 kilograms = 2 pounds, six medium apples

Milligram (mg) –A metric unit of mass. One Milligram equals one-thousandth of a gram. A grain of sand

standard unit The measurement of the mass, length, or volume of an object using either the Customary System or the Metric System

nonstandard unit Used to estimate the mass, length, or volume of an object using a comparative unit

temperature water freezes 0° C and 32°F

temperature water boils 100°C and 212°F

normal body temperature About 37°C and 98°F
